Sergio Aguero: Manchester City forward has bagged 13 goals so far this season

The Argentina striker has been in lethal form this season, going joint top of the Premier League scoring charts on eight with Liverpool's Daniel Sturridge and adding five more in four UEFA Champions League outings.

Struggling Sunderland are next in his sights - and with 22 goals conceded in the 10 games this term, the Black Cats look ripe for the taking at the Stadium of Light on Sunday.

Aguero told City TV: "I am very happy (with my tally) not only for the goals, but for the victories.

"I think most of my goals have helped to win the three points and that's the most important thing for me."

Aguero's latest strike partner Alvaro Negredo, City's summer signing from Sevilla, has also had his shooting boots on of late.

He has scored nine goals for the club to date, striking five times in his last three outings, all in different competitions.

Negredo went one better than Aguero by netting a hat-trick in the 5-2 Champions League success over CSKA Moscow in midweek and the Argentinian is happy with the combination.

"It's really good," he added. "Alvaro has arrived this year and played really well and so has the partnership between us. We have to continue on because it is an important part to help the club forward."

Pellegrini praise

Meanwhile, Aguero's compatriot Martin Demichelis has praised manager Manuel Pellegrini for asserting his own style on the City squad.

Demichelis knows the Chilean boss better than most from their shared time at Malaga and he believes the demolition of CSKA shows the message is getting through at the Etihad.

"We knew how important the game was and tried to show right from the start that we wanted it over and done with as soon as possible. The most important thing was to reach the knockout rounds," he told the Manchester Evening News.

"To get to the round of 16 was our first objective and we have achieved it.

"(Pellegrini) has a way of making sure his teams play in the way he wants, that we play effective football and that we can challenge for important things. We are in a good place now and we will have to see what happens afterwards."
